How Do You Feed a Pet Crawdad?

A pet crawdad's diet consists of shrimp pellets, green vegetables and frozen foods. Appropriate green vegetables include zucchini, cabbage leaves and shelled peas, while frozen foods that a crawdad enjoys include blood worms, fish and brine shrimp.

A crawdad hides its food and is a messy eater, so its aquarium requires frequent water changes. A crawdad is a cannibalistic animal, so an owner with more than one pet crawdad needs at least a 20-gallon capacity aquarium with places for animals to hide. It may reach up to 3 inches in length at maturity and moults regularly. Its average lifespan is two to three years, but some species live longer.
